* feat: Optimize download performance for external storage

Optimized download changes:

- Debouncing download progress persistence to reduce disk I/O.
- Switching to `FileChannel` for file writes and `Path.deleteRecursively()` for robust file system operations across various download managers (Epic, GOG).
- Dynamically adjusting download and decompression concurrency based on CPU cores for better resource utilization.
- Streamlining download status message updates in `DownloadInfo` and UI components.
- Adding an option to skip large file allocation for Steam downloads to external storage.

Also updates the JavaSteam dependency to 1.8.0.1-25-SNAPSHOT.
